I'm actually in Seoul, South Korea right now! It's currently 7:25pm and I just finished an amazing food tour of some local markets. We tried tteokbokki, gamjatang and all sorts of street foods. It was delicious!
Seoul has been wonderful to explore so far. I've seen some major palaces like Gyeongbokgung and Deoksugung, and walked around neighborhoods like Insadong. Tomorrow some friends and I are going to Lotte World for the rides and attractions.
It's really been the perfect combo of culture, history and fun activities. If you're ever in the area, I definitely recommend checking out Seoul. This website has some great info on things to do and tour options Seoul Tourism Statistics 2 23: The Ultimate Guide | GoWithGuide
